The contents of my file are:

[x fval exitflag output, final_pop] = ga(@e5, 1); options = gaoptimset('Generations',300, 'Display', 'none'); rng('default')% for reproducibility record=[]; for n=0:.05:1 options = gaoptimset(options,'CrossoverFraction', n); [x fval]=ga(@e5,1,[],[],[],[],[],[],[],options); record = [record; fval]; end

plot (0:0.05:1, record); xlabel('Crossover Fraction'); ylabel('fval')

but I can't run this file and there is an error at the following line: rng('default')% for reproducibility

Please help.
